Hi, I am trying to write a module to directly read from the disk. I have got the sector numbers where the file present using file system functions. This file starts from sector 96 on /dev/hda4 for example. The call to __getblk asbh = __getblk(bdev,96,512) makes the system hang. Do I need to add the partition offset also to the sector number? When I added partition start sector,. I am getting junk data using ll_rw_block call.
